A more modern form of idolatry that people can relate to a bit more easily was brought up already, which involves coveteousness, which isnt all that modern because the love of money ha always been around, "the love of it" is the root of all evil an is covetousness which is something we are to mortify.
For example,
Col 3:5 Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry
In fact Paul write them not to keep company with the same (but in respects to such a one who is called a brother)
1 Cr 5:11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
Covetousness (as an idol set up in the heart) being idolatry (Col 3:5)
And is show as an inward abomination (Luke 16:15)
Ezek 8:12 Then said he unto me, Son of man, hast thou seen
what the ancients of the house of Israel do in the dark,
every man in the chambers of his imagery? for they say,
The LORD seeth us not; the LORD hath forsaken the earth.
As in Luke 16:14 which shows "covetousness" (in the light of Col 3:5)
Luke 16:15 And he said unto them,
Ye are they which justify yourselves before men; but God knoweth your hearts:
for that which is highly esteemed among men is abomination in the sight of God.
Heb 4:13... all things are naked and opened unto the eyes of him with whom we have to do
Outward abominations (that which can be seen as expressed here)
Deut 29:16 (For ye know how we have dwelt in the land of Egypt;
and how we came through the nations which ye passed by;
Deut 29:17 And ye have seen their abominations,
and their idols, wood and stone, silver and gold, which were among them)
Same shown here
Acts 17:16 Now while Paul waited for them at Athens, his spirit was stirred in him
when he saw the city wholly given to idolatry.
(See Acts 17:29-30 & Rev 9:20 in respects to the same)
Paul being among the philosophers of the Epicureans (Acts 17:18) he adressed as
men of Athens(Acts 17:22) and warns in Col 2:8 saying
Col 2:8 Beware lest any man spoil you through philosophy and vain deceit,
after the tradition of men, after the rudiments of the world,
and not after Christ.
Liekwise he writes of Christ this way,
Col 2:9 For in him dwelleth all the fulness of the Godhead bodily.
And what we ought not think concerning the Godhead
when it comes to that graven by art and man's device
Acts 17:29 Forasmuch then as we are the offspring of God,
we ought not to think that the Godhead is like unto gold,
or silver, or stone, graven by art and man's device.
Shows God overlooking the time of this ignorance
(of things that ought not be done) Lev 4:2 &47
Acts 17:30 And the times of this ignorance God winked at;
but now commandeth all men every where to repent
(it also shows some men do not repent of this in Rev 9:20)
In 1 Cr, Paul touches on idolatry in a certain place in Exodus
As 1 Cr 19:7 is referring to Exodus 32:6
When Paul writes, Neither be ye idolaters, as were some of them;
as it is written, The people sat down to eat and drink, and rose up to play.
This is where the LORD said to Moses
Exodus 32:7 And the LORD said unto Moses, Go, get thee down; for thy people,
which thou broughtest out of the land of Egypt, have corrupted themselves:
The term "Corrupting yourselves" is actually shown in accord with the same, for example
Duet 4:16-18 Lest ye corrupt yourselves, and make you a graven image,
the similitude of any figure, the likeness of male or female
The likeness of any beast that is on the earth,
the likeness of any winged fowl that flieth in the air,
The likeness of any thing that creepeth on the ground,
the likeness of any fish that is in the waters beneath the earth
Go also to Duet 4:25 as well regarding corrupting one self in the same thing (see below)
(and the provoking him unto anger) with Duet 32:2 and Psalm 78:58 (which confirm)
And then Paul goes into how these things (he lists) happened unto them for ensamples
1 Cr 10:11 and they are written for our admonition, upon whom the ends of the world are come.
And he closes it by saying,
1 Cr 10:14 Wherefore, my dearly beloved, flee from idolatry
There are more but this might help some
